How to adjust
sow feeds for
summer heat
stress
Sows will consume fewer
nutrients during periods of heat
stress unless preventive measures
are taken to adjust feeds and
feeding methods.
IOANNIS MAVROMICHALIS

S

ows suffer during the summer, especially sows
of modern genetics during the lactation period.
Whereas the maintenance needs of a
gestating sow are met by a mere 2-3 kilograms feed per
day, a lactating sow nursing 14 piglets requires at least
2+(14x0.5)=9 kilograms feed per day. They rarely reach
that high level of feed intake, and this is why they milk
their offspring by burning their body fat and muscles.
And, during summer's heat stress times, feed intake
drops even further, resulting in even worse condition for
sows and low weight for piglets at weaning.
The reason sows do not consume as much feed as
they need, especially during the heat stress periods,
is because feed processing generates heat. Standing
up, chewing and swallowing feed, having it digested
and absorbed, and then metabolized, converted into
milk with waste being excreted are some of the major
processes that all produce heat, as inevitable loss
due to general thermodynamic laws. And, when the
animal tries to minimize heat stress by any means,
eating a hearty meal is no way to achieve it. Thus,
the general observation among farmers and scientists
alike is that heat-stressed animals consume less feed.
But, there are ways to partially alleviate this, some of
which involve nutrition.
